FIG. 2 is a diagram illustrating an example of the structure of pixels P of the display device 1000 of FIG. 1 , and FIG. 3 is a diagram illustrating an example of rendering by the display device 1000 of FIG. 1 .

Referring to FIGS. 1 to 3 , the display panel 101 may include a first pixel P1 having a first viewing angle and a second pixel P2 having a second viewing angle different from the first viewing angle. The first pixel P1 and the second pixel P2 may have a diamond pentile structure. For example, the first pixel P1 and the second pixel P2 each include a first subpixel displaying one first color (R) and a first subpixel displaying one second color (B). , and a first subpixel displaying two third colors (G) in a diamond shape. Here, the first subpixel displaying the third color (G) may be smaller than the first subpixel displaying the first color (R) and the first subpixel displaying the second color (B). The first color (R) may be red, the second color (B) may be blue, and the third color (G) may be green.

A pixel with an RGB stripe structure includes a subpixel displaying the first color (R), a subpixel displaying the second color (B), and a subpixel displaying the third color (G) at (X2, Y2) coordinates. Can include one each. However, a pixel with a diamond pentile structure includes two subpixels in one coordinate, and the two coordinates share a subpixel displaying the first color (R) and a subpixel displaying the second color (B). can do. Accordingly, pixels with a diamond pentile structure can display the same resolution with fewer subpixels. However, when the pixel (P) has a structure different from the RGB stripe structure, the display device 1000 displays the first color (R), second color (B), and third color (G) at one coordinate. It may be necessary to render input image data (IMG) containing data according to the structure of the pixel (P).

The first pixel (P1) may be a private pixel, and the second pixel (P2) may be a normal pixel (P2). For example, the first viewing angle may be narrower than the second viewing angle. Accordingly, when the user looks at the display panel 101 from the side, the image displayed on the first pixel P1 may be viewed with lower luminance than the image displayed on the second pixel P2.

The display panel driver 10 may drive the first pixel P1 in the first mode, and the first pixel P1 and the second pixel P2 in the second mode. The first mode may be a private mode in which a user looking at the display panel 101 from the side cannot see a normal image, and the second mode may be a general mode in which a user looking at the display panel 101 from the side can see a normal image. there is. When the first subpixel included in the first pixel P1 and the second subpixel included in the second pixel P2 are consistently grouped into one rendering unit, the user looking at the display panel 101 from the side A color shift phenomenon may occur (that is, because the viewing angles of the first pixel P1 and the second pixel P2 are different).

FIGS. 4 and 5 are diagrams illustrating an example of rendering performed by the display device 1000 of FIG. 1 using a rendering filter.

Referring to FIGS. 1 to 5 , the display panel driver 10 may render coordinate image data (CIMG) for one coordinate of input image data (IMG) for one rendering unit (RU). The rendering unit RU may include only first subpixels included in the first pixel P1 or only second subpixels included in the second pixel P2. For example, the rendering unit RU may include only first subpixels of one first pixel P1 or only second subpixels of one second pixel P2. The display panel driver 10 may render coordinate image data (CIMG) using rendering filters for the first color (R) and the second color (B). The form of the rendering filter may be determined depending on the arrangement of the first pixel (P1) and the second pixel (P2). In one embodiment, the rendering filter may be a one-dimensional rendering filter. In another embodiment, the rendering filter may be a two-dimensional rendering filter. Here, the one-dimensional rendering filter may be a filter applied in one direction, and the two-dimensional rendering filter may be a filter applied in two directions.

In one embodiment, the rendering filter may include a first rendering filter (RP1) for the first color (R) and a second rendering filter (RP2) for the second color (B). For example, the first rendering filter RP1 renders data for the first color R of the coordinate image data CIMG, and the second rendering filter RP2 renders data for the second color R of the coordinate image data CIMG. The data for (B) can be rendered. In one embodiment, the display panel driver 10 may render data for the third color (G) of the coordinate image data (CIMG) without a separate rendering filter. For example, a diamond pentile structure pixel includes a subpixel that displays one third color (G) at each coordinate, so the display panel driver 10 displays the third color (G) of the coordinate image data (CIMG). The data for G) can be used as data for the third color (G) of the rendered image data (RIMG).

For example, when a rendering filter is applied to specific coordinates, the display panel driver 10 can apply the rendering filter by locating the center of the rendering filter at the specific coordinates. This will be explained in detail through examples below.

In this case, when the second rendering filter (RP2) is applied to the (X3, Y2) coordinates, the rendered image data (RIMG) is 0.5 (1*0.5 (left) + 0*0.5 (center) to the (X3, Y2) coordinates. = 0.5) and may include data for the second color (B). The (X3, Y3) coordinates of the display panel 101 include the second subpixel for the first color (R). Data for the first color (R) of the (X3, Y2) coordinates of the coordinate image data (CIMG) is 0, and data for the first color (R) of the (X2, Y2) coordinates of the coordinate image data (CIMG) is 1.

That is, when the display panel driver 10 performs rendering of coordinate image data (CIMG) for (X2, Y2) coordinates, the rendering unit (RU) may include only second subpixels. In conclusion, as shown in FIG. 5, when rendering is performed in all coordinates, the rendering unit (RU) may include only first subpixels or only second subpixels.

The display panel 107 can display a left-eye image and a right-eye image together to provide a stereoscopic image (3D image) to the user. The left eye and right eye images are flat images (two-dimensional images) and can be arranged alternately along the horizontal direction. For example, the left eye and right eye images may be in the form of stripes arranged alternately in the horizontal direction. The barrier may divide space so that the left eye image can be observed from the user's left eye, and the right eye image can be observed from the user's right eye.

Conversely, the user's right eye may observe the right eye image through the transmission area 110, and the left eye image may be blocked by the blocking area 110 and not observed. In this way, the left eye and right eye images are divided and delivered to the user's left and right eyes, respectively, so that the user can feel a three-dimensional image.
